This adds a new BT_AMP socket option to control the use of AMP channels.
It is for use with the SOL_BLUETOOTH option level on L2CAP sockets.
Available option values are defined as:
BT_AMP_REQUIRE_BR_EDR
* Default
* AMP controllers cannot be used
* Channel move requests from the remote device are denied
* If the L2CAP channel is currently using AMP, move the channel to
BR/EDR
BT_AMP_PREFER_AMP
* Allow use of AMP controllers
* If the L2CAP channel is currently on BR/EDR and AMP controller
resources are available, initiate a channel move to AMP
* Channel move requests from the remote device are allowed
* If the L2CAP socket has not been connected yet, try to create
and configure the channel directly on an AMP controller rather
than BR/EDR
BT_AMP_PREFER_BR_EDR
* Allow use of AMP controllers
* If the L2CAP channel is currently on AMP, move it to BR/EDR
* Channel move requests from the remote device are allowed
